Walnut - Blueberry Cake

I was in the mood for baking, our youngest son was home from Winnipeg, and my parents were coming for dinner so I made some walnut-blueberry cake.  This recipe is an invention of mine that evolved from a recipe I made last Christmas.  I love the new version and walnuts and blueberries are so healthy that I figure this must be too.

Ingredients: 1 cup finely chopped walnut crumbs 1/4 cup orange juice 1 1/2 cups whole wheat flour 1 1/2 cups quick cooking oats 1 tsp baking powder 1/4 tsp alt 1/2 cup margarine or butter 1 1/2 cups firmly packed brown sugar 2 eggs 1/2 cup applesauce 1 cup blueberries
Method: 1. Combine walnut pieces and orange juice and microwave on high for 30 seconds. 2. Combine flour, oats, baking powder, and salt and set aside. 3. Beat margarine and sugar in a large bowl until light and fluffy. 4. Add eggs, beating until blended. 5. Gradually add flour mixture, mixing well. 6. Stir in walnut-orange juice mixture, applesauce, and blueberries. 7. Spread into a greased 9 x 13 pan and bake for 20-22 minutes at 350F or until centre is cooked. 8. Allow to cool on a wire rack before cutting to serve.

I've already made this recipe three times. Are you a walnut lover, like I am?  If so then you will love this cake.
